I am pretty new to Wordpress, especially when PHP programming is concerned. I am using Ciola Theme from Theme Forest. What I would like to achieve is to display a sub menu under the main menu, but only for a specific category. I added menu in theme's core-functions.php:

Now, my question is: is it possible to achieve something like on this picture?

Is there any way to make the second line of menu display only for a chosen category?

I was thinking about using if/else PHP loop and WP reference <?php is_category( $category ); ?> but unfortunately I have no idea how to do this and I do not want to break the theme... I will really appreciate your help :)

Thanks:) I added this to header.php but there was a fatal error concerning walker_97226. I changed it a bit and now the second menu appears under the main one :) Unfortunately, it displays the same content and I do not know why... here is the snippet: <?php if(is_category('teatr-wybrzeze')) { wp_nav_menu( array( 'container_id' => 'cb-main-menu', 'container_class' => 'wrap clearfix', 'theme_location' => 'main', 'depth' => 0, 'items_wrap' => '<ul class="nav main-nav clearfix sf-menu">%3$s</ul>', 'walker' => new CB_Walker() ) ); } ?>

Unfortunately I cannot render your idea in my head. The most important thing I want to achieve is that I do not wish to have make another dropdown menu. I would just want this sub-menu be visible only on the category page.
